3D Project Model – 7th Grade Tech

Last week, we made a 3D model of our projects on Tinkercad. It was a really cool experience!

Tinkercad is amazing! I was able to make the drawer exactly how I wanted it. My design had the same dimensions and everything. At first, I thought it was going to be pretty challenging, but it turned out, it’s not as hard as it seems. Anyone can design anything they want!

I started off using 4 boxes to make the bottom face of my outer box. I changed their length, width, and height to mimic the balsa wood planks. To make the rabbet joint, I took 2 of my planks and made them 1/8 of an inch shorter. Then I grouped the larger planks with the shorter ones. After that, I attached both groupings using the joint. I still wasn’t done with that face yet, though. I needed it to be 7 inches long. It was 6. So, I made one of the shorter planks another 1/8 of an inch shorter. I used 2 more boxes to make the 1 inch long grouping and made one of the planks 1/8 of an inch shorter. I then attached that new grouping with the other one. Now I finished that face! To make the top face, I just duplicated the bottom one and raised it 5 inches. To make the front, back, and sides, I used the same procedure, and then did the whole thing over again to make my inner box. Now it was time for the finishing touch. To make the handle, I used 1 more box, made it much thinner and longer, and then attached it to the front face of my inner box.

I loved using Tinkercad and thought it was a great way to plan out our projects, especially the joints. I’m looking forward to building my drawer after break!

Here is my design:

Project Diagram – 7th Grade Tech

Yesterday, we planned out our projects and made a diagram. Our projects have to be made out of balsa wood, so I chose to make a drawer. In the diagram, we have to include the dimensions, types of wood joints, and how many 36” long x 3” tall wood planks we’re planning on using.

My drawer is going to be 7” long, 10.5” wide, and 5” tall. I’m going to use rabbet joints, and I’m planning on using 7 planks of balsa wood.
